Describe how mass and distance impact an object’s gravity
The more mass an object has, the stronger the gravity.
The closer (less distance) two objects are, the stronger the gravity.

Describe the 3 types of relationships among organisms ( Predation, Competition, and Symbiosis)
1.) Predation: one organism kills and eats another organism
2.) Competition: two organisms fight over resources
3.) Symbiosis: two organisms have a close relationship that benefits at least one of them
100
Name at least 2 effects of global warming and climate change.
Sea level rise
Extreme weather
(ex. droughts + stronger storms & wildfires)
Mass extinctions

Cells have different parts called organelles that allow them to carry out functions of life.
What is the function of the NUCLEUS?
Control the cell

Describe the function of the skeletal system.
Skeletal System: Provides structure and support for your body
200
Draw and Describe what happens during a solar eclipse.
During a solar eclipse, the Moon moves between Sun and Earth, and blocks the Sun’s light from hitting Earth.
200
Describe how each of the 3 types of organisms get their energy
1. Producers
2. Consumers
3. Decomposers
1.) Producers make their own energy through photosynthesis (like plants)
2.) Consumers get their energy by eating other organisms.
3.) Decomposers get their energy from breaking down dead

)Explain which team will win this tug-of-war
2) What is the net force of this action? Why?
1)The Green team will win because it is applying greater force.
2) The net force will be 300 Newtons, because when forces are going in opposite directions you subtract them. (2500 -2200 = 300.)

Cells have different parts called organelles that allow them to carry out functions of life.
What is the function of the MITOCHONDRIA?
Creates energy
200
Describe the function of the muscular system.
Muscular System: Allows your body and organs to move
300
What is the continental drift theory?
The continental drift theory suggests that the continents were once joined together and have moved apart over time.
300
The increase of humans in the world is causing some problems. Name 2 of them.
1. Cutting down of too many trees
( this is called deforestation)
2. Burning fossil fuels causes global warming
3. Increased pollution
4. Increase in spread of disease
300
Based on Newton’s 3rd Law, if the car and truck below collide, which vehicle will exert more force?
Both vehicles will exert the same force!!
300
Cells have different parts called organelles that allow them to carry out functions of life.
What is the function of the VACUOLE?
Stores important materials for the cell
300
Describe the function of the
circulatory system
Circulatory System: Moves
important things through your
body by your blood
400
What are homologous structures?
Homologous structures are body parts of different organisms that look similar but often have a different job.
400
Describe a divergent plate
boundary.
Divergent plate boundaries occur when 2 plates spread apart - creating rift valleys
400
What is the role of convection currents in the Earth’s mantle?
Convection currents cause:
hot magma to rise
then cool and sink
making Earth’s tectonic plates move and create mountains, earthquakes,etc.
400
Cells have different parts called organelles that allow them to carry out functions of life.
What is the function of the CHLOROPLAST?
In plant cells, captures sunlight to turn into food for the cell
400
Describe the function of the
respiratory system.
Respiratory System: Allows you to
breathe in oxygen and breathe
out carbon dioxide
500
1) Describe a unicellular organism.
2) Describe a multicellular organism.
1. Unicellular organism - has just ONE cell that carries out all functions of the organism’s life
2. Multicellular organism - has many specialized cells that carry out specific functions
500
What is the Sun's role in the water cycle?
The sun provides energy to evaporate
the water and start the cycle
500
Oil, coal and natural gas are fossil fuels.
How do fossil fuels form on Earth?
Fossil fuels are formed when dead plants and animals are broken down, buried and squeezed by heat and pressure over millions of years.
